Histopathologic examination of the kidney in a 12-year-old Caucasian girl with asymptomatic haematoproteinuria. a. Low-power magnification of five glomeruli showing cellular crescents (Jones stain; original magnification, ×10). b. High-power magnification of one noncircumferential cellular crescent with rare intracapillary neutrophils (Jones stain; original magnification, ×40). c. Immunofluorescence showing granular deposits of C3 (+++) within the mesangium, glomerular capillary loops, and tubular basement membrane (original magnification, ×40). d. Electron microscopy showing intermediate electron-dense deposits within the glomerular capillary loops and mesangium (original magnification, ×40,000).
